The HN response seems strongly negative so far. Can someone educated in the space play devil’s advocate and share ideas on why it might be a good move?
We don't know if vaping is safe. So, using the precautionary principle, you could ban it or restrict it for non-smokers until we get more data. Public Health deals with population sizes, not individuals. Imagine 100,000 non smokers take up vaping. Some of them will be harmed (because nothing is risk free). We need to have a discussion about how many people being harmed is an acceptable risk, and how we communicate that risk to users.
And there's some evidence that people who start vaping with nicotine-containing products will become addicted to nicotine and move to tobacco. That isn't helped by companies going out of their way to design a more addictive vaping product. This is another reason to restrict vaping products and only allow them to be used by people who smoke tobacco.
Personally, I disagree with the ban and I prefer Public Health England's stance. I think banning vaping while allowing internal combustion engine vehicles on the road is dumb. https://www.gov.uk/government/news/e-cigarettes-around-95-le...
